Abstract: An actuator for converting linear motion into rotational motion comprises a pressure chamber for receiving a working fluid, an actuator housing (1) having a longitudinal slot provided therein, a yoke frame (3) provided within the housing, a shaft (A,B) passing through the longitudinal slot into the yoke frame (3), a thrust pin (4) mounted on the shaft (A,B) within the yoke frame (3), return means (5) for countering working fluid pressure and an override device (7-10) which allows forces stored within the actuator to be released in the event of failure of the actuator.
