A torque transfer device in the drive train of a motor vehicle for transferring torque between a drive unit and a shaft rotatable about a rotation axis, including: a hydrodynamic torque converter, which includes a converter cover, connectable to the drive unit, and which can be coupled through a pump shell to a turbine shell for torque transfer, which can be bridged by a torque converter lockup clutch for torque transfer, which comprises a piston, movable in an axial direction within a range towards the cover in order to clamp a friction liner support with at least one friction liner between the piston and the cover for torque transfer. A friction ring is disposed between the piston and the friction liner support, and the friction ring is movable in an axial direction within a range between the piston and the friction liner support and connected to the converter cover.
