Can anyone suggest how I would go about describing T(t) in terms of
theta(t), theta'(t), I, m, and r?

Sounds like a very cool idea! Except don't they use electronic
controls to drive bells instead of people nowdays?

For a real shaft, at some point in time, the total torque applied = I
* angular acceleration. Your applied torque would be the sum of:
Weight: Some simple trig with theta, m and r.
Rope: Trope=F*r

I think you'd have to control the speed as well as the torque. For
example if the guy lets go, the motor isn't driving any load but it
should still rotate with the correct angular acceleration.
