1. A door actuator linkage, comprising:
a lever extending along a longitudinal axis, which merges into a linkage head with an offset,
wherein the linkage head is formed for rotationally fixed mounting on an output shaft of a door actuator,
wherein a free space for cable routing is formed by the offset, and the free space is delimited by the linkage head and by an offset surface of the lever,
wherein the lever protrudes up to an imaginary boundary surface, which is defined perpendicular to the longitudinal axis, and wherein the offset surface is withdrawn partially from this boundary surface to expand the free space.
