Abstract
A camshaft adjuster for adjusting the phase angle between a crankshaft and a camshaft of an internal combustion engine comprises an actuator, in particular, an electric motor, and an adjustment module, which comprises a drive element, which can be driven by the crankshaft, and an output element, which can be rotated relative to the drive element to a limited extent and which is provided to be securely coupled to the camshaft, wherein a signal generator, which is arranged so as to be fixed in position on the internal combustion engine and which has an inductance, is inductively coupled to a measurement circuit, which is integrated into the adjustment module and which has at least one resonant circuit component having electrical properties that depend on the said phase angle.
