In order to protect an actuator system for a movable surface in a reliable manner, while also protecting the movable surface in the event of a system failure, the actuator system includes a power drive unit connected to one end of an input shaft. An actuator is disposed on the input shaft having multiple output stages normally driven by the power drive unit through the input shaft with the mutiple output stages being operatively associated with the movable surface for driving movement thereof. In order to provide dual load path shafting together with incorporating fail safe actuator construction, the actuator system also includes a feedback shaft extending from the actuator to the power drive unit and a torque sensor operatively associated with the feedback shaft.
