Abstract
An electro-mechanical actuator is provided resisting back driving of a gear train in at least one direction. The actuator includes an internal gear train. A clutch is coupled to an output of the gear train and transmits a driving force from the gear train to a clutch output. When a back driving force is applied to the clutch output in at least one direction, the clutch assumes a locked configuration. When the clutch is in a locked configuration the clutch resists rotational movement of the output and back driving of the gear train.
