Abstract
A camshaft phaser or camshaft adjuster for an internal combustion engine is disclosed. The camshaft adjuster includes a rotor, and a stator disposed about the rotor in a slideable engagement such that the stator and the rotor are rotatable relative to each other. A trigger wheel is configured to interact with an associated sensor for detection of an angular speed or position of the trigger wheel. A drive plate is configured to be non-rotatably fixed with an inner camshaft and rotatably coupled to the trigger wheel. In various embodiments, the trigger wheel has an axial face that defines an opening, and the drive plate has a tab with an axially-extending portion extending through the opening in the trigger wheel.
