In a combined clutch and brake apparatus, a pressure means is shifted by a piston and a spring between two positions for frictionally coupling a casing, whose hub portion is connected with a shaft, either with a rotary friction means or with a blocked friction means. Bolts connect the casing end walls, and pass through the cylinder chamber, a piston in the cylinder chamber, and the pressure means which is biassed to abut the piston, and is shifted by pressure fluid in the cylinder chamber in one direction, and by a spring in the opposite direction. Due to the position of the bolts, the apparatus is compact, has a small outer diameter, and comparatively wide annular friction faces.
