A flexible disc-like coupling element is provided for use in a flexible coupling which joins a driving shaft to a driven shaft of a drive train apparatus. The disc-like coupling element includes a substantially arcuate shaped hub portion at least partially defining and at least partially surrounding a central aperture. The hub portion has a radial dimension as defined from the central aperture of the disc-like coupling element. The hub portion includes a structure for flexing across the radial dimension within the plane of the disc-like coupling element. The disc-like coupling element also includes a plurality of lobes spaced from the hub portion and connector portions corresponding to each lobe for connecting the corresponding lobe to the hub portion. Each lobe has a pair of substantially arcuate shaped arms joined together adjacent a corresponding connector portion. The arms extend away from one another in substantially opposite directions and terminate in free ends. The free ends of the arms having attachment mechanisms for attaching the disc-like coupling element to other elements of the drive train apparatus. The attachment mechanisms are located at a substantially identical radial distance from the central aperture of the disc-like coupling element.
