A device for coupling a universal joint shaft to a power take-off shaft () of a tractor has a first coupling mechanism () that is non-rotatably arranged on the universal joint shaft. A second coupling mechanism () is non-rotatably arranged on the power take-off shaft () of the tractor. The first and second coupling mechanisms can be non-rotatably coupled to transmit torque. A coupling shield () is provided to couple the coupling mechanism (). The first coupling mechanism () is at least indirectly rotationally supported on the coupling shield (). A locking mechanism (') projects from the coupling shield (). A bracket () is attachable on the rear of the tractor. The bracket () has at least one locking device (&#x2032;) that is displaceable between an unlocked position and a locked position. The locking device (&#x2032;) is displaced from the unlocked position into the locked position. The locking device (&#x2032;) interacts with the locking members (&#x2032;) of the coupling shield () to pull it towards the bracket (). The first coupling mechanism () is transferred into a coupling position to couple it the second coupling mechanism ().

Device for coupling a universal joint shaft with a power take-off shaft of a tractor

A device for measuring torque in a drive assembly includes a torque-loaded torsion element ( ), such as a shaft, and a reference element ( ) surrounding the torsion element ( ). The reference element is correspondingly tubular in shape. A first tube end ( ) of the reference element ( ) is firmly connected to a first shaft end ( ) of the torsion element ( ). A second tube end ( ) of the reference element ( ) is supported on the second shaft end ( ) of the torsion element ( ). The two tube ends ( ) are each associated with a transmitter element ( ). The relative position of the transmitter elements ( ) in the direction of rotation around the rotational axis ( ) is recorded by a sensor element ( ). The sensor ( ) is associated with a housing ( ). The sensor ( ) generates a signal each time the two transmitter elements ( ) pass and transmits signals to an evaluation unit ( ). The evaluation unit ( ) determines the torque applied from the offset of the signals.
