1. A drive and/or adjustment device for driving and/or adjusting a rotatable assembly comprising a large rolling bearing ring of a wind turbine or a slewing gear of a construction machine or of a hoist, comprising an output element for rotationally driving and/or adjusting the rotatable assembly, a transmission which is connected downstream of the output element and has at least one torque-transmitting gear, and an overload safety mechanism for the rotatable assembly; wherein the overload safety mechanism is on the at least one torque-transmitting gear, wherein the gear is divided and comprises two gear parts that are torque-transmittingly interconnected via spur toothing and held axially in spur toothing engagement by an axial securing means which yields at a predetermined axial loading between the gear parts, wherein the transmission comprises a planetary gear with a divided sun gear forming the overload safety mechanism.
