Apparatus for transmission of torque in the power train of a motor vehicle has coaxial rotary first and second torque transmitting devices, each of which can constitute a simple or a composite flywheel, and a torsional vibration damper operating between the two devices. The damper is installed in an annular chamber which is sealed at its periphery and is flanked by two sidewalls of the first torque transmitting device. The damper includes a washer-like partition which is affixed to the second torque transmitting device and has arms extending radially outwardly into the chamber. The radially inner part of the annular chamber is sealed by annular seals having annular carriers borne by the sidewalls at opposite sides of the partition, and deformable annular lips secured to the carriers and bearing upon the respective sides of the partition. The carriers and the lips consist of different materials and the seals serve to prevent penetration of impurities into and/or the escape of lubricant from the chamber. Such lubricant is in contact with coil springs which form part of the damper and oppose rotation of the torque transmitting devices relative to each other.
