A twin mass flywheel (10) in which two co-axially arranged flywheel masses (11,12) are mounted for limited angular rotation relative to each other and a plurality of pivotal linkages (40) interconnect the two flywheel masses. Each linkage comprises a first link (41) pivotally connected (43) to one (12) of the flywheel masses, a second link (42) pivotally connected (44) to the other (11) of the flywheel masses, and a pivot (45) for pivotally connecting the first and second links. A resilient member in the form of an elastomeric torsion unit (46) or spring (36) is associated with the pivotal connection (44) of at least one link (42) with its associated flywheel (11) for controlling the relative rotation of said flywheel masses (11, 12).
