Basic Screwdriver/Screw Model

I am attempting to model the stress/strain in a standard philips screw and screwdriver when the two act together.
For simplicities sake I am using a simple phillips drill bit (since it has more basic geometry than a screwdriver) and a basic philips screwhead. Both are CAD models imported from Solidworks. I am using a Solid Mechanics study, I applied a Fixed Constraint boundary to the screw, and I created a contact pair between the head of the bit and inside of the screwhead.
However, I cannot figure out how to apply a Moment to the screwdriver (in this case the drill bit) to simulate the twisting motion. After extensive googling, the only place I can find an applied Moment in COMSOL is in the "Beam" physics section, but I am not sure if I can/should use that in this situation.
In short, what is the best way to simulate a 7 Nm twist of a philips screwdriver acting on a screw?
Thank You!
