A metal flexing coupling for connecting two rotatable shafts in end-to-end relationship is disclosed having reversible, coupling hubs for mounting on the opposed shaft ends. Laminated metallic flexible elements are secured to the respective hubs and to a center member using an alternating and staggered bolting pattern, such that the center member is secured to the hubs only through the flexible elements. The alternating pattern allows the coupling to flex to accommodate misaligned shafts or shafts exhibiting end float.
