Abstract
A camshaft phaser for a concentric camshaft assembly includes a stator defining a cavity and configured to receive power from an engine crankshaft. A rotor is supported within the cavity and is rotatable relative to the stator. A drive adapter has a shank and a head. The shank is extendable through the rotor and is configured to engage with an inner camshaft. The head has an end face defining a first key feature and a continuous groove. A drive plate is fixed to the stator and includes a radial wall defining a second key feature engageable with the first key feature to rotationally fix the drive adapter to the drive plate. An annular gasket is received in the groove and is sealable with the wall.
