A friction clutch for a drive train of a motor vehicle generally has a torsional damper with at least one hub and hub disc concentric to an axis of rotation, and cover plates located on both sides of the hub disc which are non-rotationally connected together and held at a distance from one another. Coil springs can be located in apertures of the hub disc, on one hand, and in the cover plates on the other hand. The apertures can be designed so that the coil springs, located in the apertures of the cover plates, in spite of the fact that the coil springs are held without stress on their ends, cannot come loose from the apertures. To achieve this, the edges with which the ends of the respective coil springs come in contact can be provided with indentations which are designed for the radial release of the respective outermost windings of the coil springs.
