Mating a bolt thread with a nut

I have an assembly that consists of a bolt and a nut.  the threads are modeled into the parts.

I want to mate them so when I move the bolt it rotates around the threads.  I also want to apply a motor in a motion study the nut will rotate around the bolt correctly to the the threads.

files are attached, for sW 2010
