1. A threaded spindle for a spindle drive, the threaded spindle comprising an outer thread, and
a coupling element, comprising:
a coupling portion, and
a receiving portion which is formed integrally with the coupling portion,
wherein the receiving portion extends in a hollow-cylindrical manner along an axis having an axial receiving opening in which a securing portion of the threaded spindle is coaxially received and the coupling portion is flattened transversely with respect to the axis relative to the receiving portion and has a connection means,
wherein the receiving portion and the coupling portion are formed from a continuous, integral pipe portion, and wherein the receiving portion has a plastic deformation which is connected in a positive-locking manner to a plastic deformation of the threaded spindle, and
wherein the coupling portion has a pressing portion in which the pipe portion is plastically compressed flat transversely relative to the axis.
