Hi there, we have a new member of the club, and I am curious toward your suggestions of how I may go about teaching him to control the amount of power he is putting behind his techniques.

This is a video of when I first sparred with him, on first contact. He and I had never met each other before, and I must couch that my role in this was as the leading instructor for the group. I was not trying to go hard, merely to use deliberate mistakes on my part, and watching out for theirs, as a teaching tool to help them become better. I am in the black, he the white.
How can I help this person with gaining control, so I may allow them to practice in a contact pretext, with others of our group?
I feel more target practice might help.
This comes down only to your interpersonal skills and how much influence you can develop over how he behaves in your training sessions. No amount of physical training is going to change the mindset of someone who (perhaps subconsciously) thinks that they can't achieve power without trying to 'muscle' the movement.
There are some nice demonstrations that can illustrate the point, though. I find this is a great reason for the existence of board breaking, for example. Set up some boards and break them yourself with pure, effortless looking technique. Then have your boy try to muscle through them and fail. It will need to be a big stack for this wot work by the sound of your description.
Alternatively, have him swing a simple horizontal backfist strike at a kidney pad. There's less danger of taking it to the face, and it's great for demonstrating that 'muscling' the technique is a poor relation of good waist-twisted technique.
Keep him banned from sparring and contact work until he can adequately demonstrate that he understands both that a) power does not come from muscle tension and that b) 'muscled' power causes tension and inaccuracies, and is likely to result in him injuring his training partners. He needs to be told in no uncertain terms that the people who he is training with are friends, not enemies, and when friends get hurt due to his poor self-control, they don't want to be his training partners anymore.
Lastly, and hopefully not necessary, it should be fairly easy for you to evade someone with so little experience and control; avoid the incoming and give him too much contact in return every time until he backs off. Make it clear there and then with each strike why you are doing this and that it is deliberate. In my own personal experience, and this happens seldom, people who don't back off in this situation decide to leave and not come back, when they realise that muscle will only get them so far.
