The invention relates to an assembly, comprising a rotatably supported shaft (03), a drive for driving the shaft (03) in a driving direction, and a torque module (09) for magnetostrictively sensing the torque of the shaft (03). The assembly according to the invention is characterized in that a freewheel (10) is arranged between the drive and the torque module (09), which freewheel serves to transmit torques in the driving direction and to block the transmission of torques against the driving direction. The invention further relates to a drive train (01) of a broadcast spreader, comprising at least one spreading disk fastened to a shaft (03) for conjoint rotation, a drive for rotationally driving the shaft (03) in a driving direction, and a torque module (09) for magnetostrictively sensing the torque of the shaft (03). A freewheel (10) is arranged between the drive and the torque module (09), which freewheel serves to transmit torques in the driving direction and to block the transmission of torques against th
