A/C Specific
I think you'll find the answer is aircraft specific. Can't tell you for anything other than the B757, but yes, the controls move (yoke and throttles) - as they always do when the autopilot is in operation. As PF, you keep a light touch on both ready to take over should anything go wrong.
You can override the AP using the breakout function - can't remember the force required off the top of my head - but you are basically creating a highly unstable situation during a critical phase of flight.
Hope this helps.
