Directly driven extruder with an adapter

Extruder device with an extruder worm (4) and a worm drive (1, 2),

• which (1, 2) includes a drive motor (1),
• which exhibits a rotor (8),
• which during operation is connected to the extruder worm (4) in such a manner that the rotor (8) and the extruder worm (4) rotate at the same speed during operation and
• which can be connected to detachable torque-transmitting elements (6, 14, 15), which transmit torque between the rotor (8) and the extruder worm (4) and which can be detached when retrofitting work occurs,
• where the detachable torque-transmitting elements (6, 14, 15) include a torque transmission point, at which torque is transmitted from a bushing (14) to a connecting section (6), which is at least partially encompassed by a bushing (14), characterized in
• that the bushing is fastened on a face side of the rotor, and
• that the torque transmission point in the axial direction is located outside the rotor (8).
