Abstract
A rotary drive for actuating a valve element of a valve fitting, having a housing, which has a drive device and a pivot-mounted driven shaft which can be driven by the drive device and which can be coupled to the valve element, and a position detection device for detecting a position of the driven shaft, wherein the position detection device has a magnet module attached to the driven shaft in a torque-proof manner and a sensor module which is fitted onto or into the housing and is designed to detect a magnetic field measurement value according to the magnetic field generated by the magnet module. The the magnet module and/or the sensor module is attached such that it can be removed from the rotary drive, and the rotary drive includes a control device, which is adapted to determine if the magnet module or the sensor module is removed from the rotary drive.
