Torque transmission device and drive train for a motor vehicle

A torque transmission device for a motor vehicle includes a rotor carrier mounted rotatably about an axis of rotation, an input hub, an output hub, and a torsion damper. The rotor carrier has a fastening portion and a first flange portion. The fastening portion and the input hub are arranged on a first axial side of the first flange portion and are connected to the first flange portion. The torsion damper has an energy storage element and a damper output part, which includes a second flange portion and an actuating portion operatively connected to the energy storage element. The second flange portion is torque-transmittingly connected to the output hub and the actuating portion. The second flange portion is situated axially between the first flange portion and the output hub. The first flange portion has a through-opening through which the actuating portion passes.
