A flexible coupling for torque transmission, which comprises an annular coupling element of flexible material having metallic bushings for the reception of securing screws and disposed between the input side and the output side of the coupling. The coupling element is mountable free from pretension by the securing screws directed alternately in radial and axial direction. A cylindrical armature sleeve is provided which constitutes one coupling part and is smooth and free of projections and recesses except threaded bores for the securing screws, as well as hold the securing screws disposed in radial direction. A flange hub constitutes another coupling part and is smooth and free of projections and recesses except threaded bores in the flange hub for the securing screws disposed in axial direction with a plane surface of a flange of the flange hub. The armature sleeve and the flange hub cooperate with each other. The elastic parts of the coupling have a pressure pretension by the securing screws disposed in radial direction. Metal bushings directed in radial, as well as in axial direction are provided and received within the cross-section configuration of the cross-section of the coupling element for the reception of the securing screws in the direction to its coupling-sided securing engagement face relative to the coupling element including columnar connecting members between the bushings secured in the other direction are disposed projectingly, and the coupling element has in its unmounted tension-free state the configuration of an irregular polygon.
