• 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 coupling portion has a pressing portion in which the pipe portion is plastically compressed flat transversely relative to the axis.

A steering column for a motor vehicle, the steering column comprising:

• a carrier unit configured to fit to a vehicle body,
• an adjustment unit held by the carrier unit,
• a steering spindle rotatably supported in the carrier unit,
• an adjustment drive which is arranged between the carrier unit and the adjustment unit and by which the adjustment unit can be displaced relative to the carrier unit,
• wherein the adjustment drive is a spindle drive, comprising a rotatably drivable spindle nut, in which there engages a threaded spindle which has an outer thread and on which there is secured a coupling element with a receiving portion which is formed integrally with a coupling portion, wherein the receiving portion extends 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, wherein the coupling portion has a pressing portion, in which the pipe portion is plastically compressed flat transversely relative to the axis.

A coupling element for fitting to a threaded spindle, the coupling element comprising:

• a coupling portion,
• a receiving portion which is formed in one piece with the coupling portion,
• wherein the receiving portion extends in a hollow-cylindrical manner along an axis having an axial receiving opening for receiving the threaded spindle, and
• wherein 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 metal sheet portion, wherein the receiving portion has a pipe portion in which the metal sheet portion is bent over in a tubular manner about the axis.

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 metal sheet portion, and
• wherein the receiving portion has a pipe portion in which the metal sheet portion is bent over in a tubular manner about the axis around the threaded spindle and is connected to the threaded spindle.

A steering column for a motor vehicle, the steering column comprising:

• a carrier unit configured to fit to a vehicle body,
• an adjustment unit held by the carrier unit,
