A scroll-type apparatus includes a radial compliant drive. The radial compliant drive is achieved by using a set of corresponding flat driving surfaces with one of the drive surfaces being located on a drive bushing and the other being located on a crankshaft. The drive bushing is provided with a pair of flat drive surfaces with each flat drive surface of the drive bushing capable of mating with the drive surface of the crankshaft in a different geometrical fashion to provide two different radial driving loads.
