Torsion bar backing out??

OK, I thought you meant the rear socket where the clip is, sometimes they rust loose and spin in the frame.
As for what direction, I'd assume you are turning it right (righty tighty as your facing the bolt head). I don't know, is there a lot of resistance when you turn it? I usually jack the car up to take the weight off the suspension when I adjust them. It shouldn't move anywhere from where you had it set.
