Abstract
A rotary actuator comprises a planetary gear assembly having a sun gear, a drive input, and a drive transmission whereby rotary device is transmitted between the drive input and the sun gear. The drive transmission incorporates a brake operable to apply a braking load to the sun gear in the event that the torque applied to the drive transmission in at least a first rotary direction exceeds a predetermined level.
