Abstract
A variable cam timing apparatus () and method of assembly for transmitting rotational torque between a driving rotary member () and a driven rotary member (). The flexible coupling () can include an axis of rotation coinciding with, and an outer peripheral edge () extending at least partially around, or completely surrounding, a common rotational axis of the driving rotary member () and the driven rotary member (). The flexible coupling () including a flexible body () having a plurality of apertures () formed therein at angularly spaced positions relative to one another for connection therethrough with respect to the driving and the driven rotary members () permitting adjustment for perpendicularity and axial misalignment, while maintaining a torsionally stiff coupling between the driving and driven rotary members (). A cam phaser () and concentric camshaft () define at least in part the driving rotary member () and the driven rotary member () for operating a poppet-type valve () of an internal combustion engine () of a motor vehicle ().
