Abstract

A rotary drive device includes a housing element, a drive shaft and a driven shaft, both rotatably mounted in the housing element, a transmission device that transmits torque from the drive shaft to the driven shaft, and a braking device configured to counteract rotation of the drive shaft. The braking device includes a drive shaft input element, a braking element connected to the housing element for conjoint rotation, and a coupling element adjustable with respect to the input element. A braking force exerted by the braking device is greater when the coupling element is located in a first position than when located in a second position, and the coupling element assigned to the driven shaft so that adjustment from the first position to the second position is triggered by exceeding a threshold value of the difference in torque between the drive shaft and the driven shaft.
