Rotary mowers, bush hogs, etc have them in the drivetrain to protect them when the operator hits a stump or rock. You may have to do some adapting. One way is to have a flanged hub on the shaft, a layer of friction material, a sprocket that is piloted on the hub, another friction plate, and a spring loaded plate to clamp it all together. Common on USA style PTO's.
