1. A steering device with a rotatably mounted steering shaft, comprising:
an input shaft;
an output shaft formed separately from the input shaft; and
a steering sensor unit configured to inductively detect at least one item of steering information, the steering sensor unit including at least one sensor element and at least two rotor elements configured to interact with the sensor element, wherein:
a first rotor element of the at least two rotor elements is connected for conjoint rotation to the input shaft and has a first rotor portion which is associated with the at least one sensor element and extends perpendicularly with respect to the steering shaft,
a second rotor element of the at least two rotor elements is connected for conjoint rotation to the output shaft and has a second rotor portion which is associated with the at least one sensor element and extends perpendicularly with respect to the steering shaft,
the second rotor element has a plurality of fastening lugs fastened to the output shaft,
the first rotor element defines a plurality of leadthrough openings that extend entirely through the first rotor element in an axial direction, and
each of the plurality of fastening lugs extends in the axial direction through a respective one of the plurality of leadthrough openings.
