| This subclass is indented under subclass 331. Subject matter wherein one of the gears in said planetary
gear transmission is moveable in an axial or radial, nonrotary,
direction with respect to another of the gears to accommodate proper
alignment of the gears; or which include connecting means between
two shaft elements in a drive train* which permits a limited amount
of relative movement between said shaft elements or permits rotation
of said shaft elements when they are misaligned or angularly related;
or which provides a flexible support for said planetary gear transmission;
or which provides a resilient connection between a gear and its
supporting or driving member.
