Third person shooter script, turns whole player how do i make just the upperTorso turn?

I found this Third person shooter script that allows the character to aim like in third person. It works with r6 and r15 i am using r15. I am trying to modify it so the UpperTorso turns. It is currently turning the whole player, how do i add a line of code were instead of the whole player turning in the direction of the cross hair, just the UpperTorso. this is the script im trying to modify.
