A fluid-powered rotary actuator for providing end-limited rotational drive to another device, having a splined output shaft rotatably supported within a body and a drive end coupled to the other device; a linear-to-rotary transmission providing relative rotational movement between the body and the shaft, the transmission including a piston for application of fluid pressure to first and second side thereof to produce linear movement of the piston in first and second opposed directions which movement is translated into rotational movement of the shaft; a threaded body end cap adjustable from an end of the body remote from the drive end to permit selective longitudinal positioning of the cap relative to said body, and having a stop surface for engaging the second side of the piston and limiting its travel in the first direction; and an elongated sleeve adjustable from the remote end and extending from outward of the cap at the remote end to beyond the piston, and having a stop shoulder for engaging the first side of the piston and limiting its travel in the second direction, the cap and sleeve providing limits to rotational movement of the shaft.
