A torsional vibration damper at a bridge clutch of a hydrodynamic torque converter is constructed with a drive-side transmission element which can be brought into a working connection with the converter housing and is connected with a driven-side transmission element by a coupling mechanism provided with an energy accumulator acting in the circumferential direction. The driven-side transmission element is fixed with respect to rotation relative to a driven-side structural component part of the torque converter. The transmission elements, together with the coupling device, form a gear unit with gear unit elements via which the secondary diagonal of the mass matrix is occupied for forming a decoupling frequency. The decoupling frequency can be adapted to a predetermined resonant frequency of the drivetrain of a motor vehicle by an appropriate configuration of the mass moments of inertia of the gear unit elements contained in the mass matrix and of the springs of the energy accumulator given in a stiffness matrix.
