A rotary actuator includes a motor powering a harmonic drive during normal operation. The rotary actuator includes a brake that can selectively hold the position of the harmonic drive even in the event of main power loss to the rotary actuator. The rotary actuator includes a clutch arrangement that allows freewheeling of the harmonic drive in only a first rotational direction in the event of power loss to the rotary actuator. The clutch arrangement also enables movement in the second rotational direction without transferring to the motor when the counter-load on the harmonic actuator exceeds a predetermined amount of force.
