A clutch device includes a clutch hub radially inward of a clutch rotational axis on a hub side of the device, a clutch flange radially outward on a flange side of the device, a spring device through which the hub and flange sides support each other in the circumferential direction in a resilient torque-transmitting manner, the spring device having a spring element that, in the circumferential direction, is supported at opposite ends by first and second support components assigned to the flange and hub, and a stop device through which the hub and flange sides support each other in an interlocking torque-transmitting manner in the circumferential direction when a defined maximum twist angle is reached between the hub and flange sides, wherein the stop device has first and second interlocking elements integrally formed with the first and second support components that interlock when the maximum twist angle is reached.

A vibration device for generating various vibration signatures or characteristics is provided. This various vibration signatures or characteristics allow a single vibration device to be used to test and replicate failures in a subject device across a broad range of vibration signatures or characteristics transferring to the subject device. The vibration devices includes a pair of spaced-apart plates, each defining a slot therein. An adjustable fastener connects the upper and lower plates and extends through the upper and lower elongated slots. A vibrator is fastened to the upper plate via the upper elongated slot. To enable the vibration signatures or characteristics to be varied, the fastener is adjustable in a vertical direction to alter the distance between the lower plate and the upper plate, and is adjustable in a horizontal direction along the upper and lower slots. The motor can also translate along the upper elongated slot.
