A scroll compressor has a pair of interleaved scrolls. An Oldham coupling is attached to the orbiting scroll to prevent rotation of the orbiting scroll. This Oldham coupling has keys that are slidingly received in slots. One side of each key is loaded while the opposite side is non-loaded. The non-loaded side of the key has a stepped or profiled surface to provide clearance to allow deflection of the key. In another embodiment, the stepped or profiled surface is provided on the non-loaded side of the slot.

1. A scroll machine comprising:an outer shell; a first scroll member disposed within said shell, said first scroll member having a first spiral wrap projecting outwardly from a first end plate; a second scroll member disposed within said shell, said second scroll member having a second spiral wrap projecting outwardly from a second end plate, said second scroll wrap being interleaved with said first spiral wrap to define a plurality of moving chambers therebetween when said second scroll member orbits with respect to said first scroll member; a coupling disposed between said second scroll member and a non-moving component of said scroll machine, said coupling having a ring and a first key extending from said ring, said first key being disposed within a first slot defined by said second scroll member, said first key having a loaded surface in contact with said second scroll member and a non-loaded surface defining a first clearance with said second scroll member, said first clearance with said second scroll member having a first dimension proximate to said ring and a second dimension distal from said ring, said second dimension being greater than said first dimension.
