A fluid-actuated rotary drive device is provided, with a housing (2) in which is formed a working chamber (3), in which is a swivel piston (18) able to swivel around a central axis (5). Also fitted or able to be fitted in the working chamber (3) is a space divider and stop unit (38), comprised of a space divider element (24) and at least one stop element (42) fixed to the former. The components of the space divider and stop unit (38) are fitted to one another by snap-in connection, so that the space divider and stop unit (38) is easy to handle during its installation in the working chamber (3).
