Abstract
A screw actuator comprises a screw shaft for threaded engagement with an actuator output device such that rotation of the screw shaft causes linear movement of the actuator output device; and a motor for driving rotation of the screw shaft. A no-back device is included for restricting movement of the screw shaft in response to feedback torque applied due to external forces on the actuator output device.
