A torque transmission device consists of a resilient coupling between two shafts. The resilient coupling comprises an assembly mounted on one shaft and provided with a plurality of cylinders each having a piston and a cam arrangement mounted on the other shaft and controlling the piston as regards movement in their respective cylinders upon angular displacement between the two shafts under load conditions. A fluid-filled passage connects the cylinder heads with an outlet for indication or control purposes. The cylinders may be arranged radially with respect to the shaft axes or parallel thereto. A suitable indicating instrument may be connected to the outlet for torque sensing and the device may also be used for torque limiting by connecting to the outlet, means, for instance a metallic bellows, which, at a predetermined value of fluid pressure, increase the volume occupied by the fluid. In addition, the device may be used as a fluid clutch by the provision of manually-operated means for increasing the volume occupied by the fluid.
