A flexible drive shaft coupling with two stage torsional flexibility. The flexible drive shaft coupling allows axial, radial, and bending misalignment of the input and output shafts while vibrationally isolating the shafts from one another. At low torque, power is transmitted from the input shaft through an elastomeric ring to the output shaft. At higher torque the elastomeric ring is deformed to allow contact between a less resilient snubber assembly and a drive plate mechanically connected to the output shaft. Power is transmitted through less resilient snubber assemblies which provide for greater power transmission. The axis of the coupling can be provided with a flexible spool assembly to allow transmission of exhaust mass from the input shaft to the output shaft.
