ABSTRACT:
An electromechanical actuator is provided which is capable of disconnecting the output shaft and the drive mechanisms in such a way that, in the event of either a rotational or translational failure during operation, the output shaft can be effectively freed in such a manner that it will not resist the motion produced by other actuators which have not failed.
