The invention relates to a torque transmission device, in particular in the drivetrain of a motor vehicle, for transmitting torque between a drive unit and a shaft which is rotatable about a rotational axis, in particular a transmission input shaft, having a hydrodynamic torque converter which comprises a converter cover which can be or is connected to the drive unit and which can be coupled by means of a pump wheel, for torque transmission, to a turbine wheel which, for torque transmission, can be bypassed by means of a converter bypass clutch which comprises a piston which is movable in the axial direction to a limited extent in the direction of the converter cover in order to clamp a friction lining carrier having at least one friction lining, for torque transmission, between the piston and the converter cover. The invention is characterized in that a friction ring is arranged between the piston and the friction lining carrier, which friction ring is movable to a limited extent between the piston and the friction lining carrier in the axial direction and is rotationally fixedly connected to the converter cover. |
