drug delivery device assembly The present invention relates to a drug delivery device assembly (1) comprising a housing (2), a dose element (22), a guide rail (42) and a spring element (26). the dose element (22) is adapted to be rotated in a dose setting direction with respect to the housing (2) to adjust a dose of a drug (5) and to be rotated in a dose distribution direction with respect to to the housing (2) to distribute the set dose. the dose element (22) comprises a guide aspect (46). the guide rail (42) is configured to mechanically cooperate with the guide aspect (46). guide track (42) is configured to mechanically cooperate with guide aspect (46). the guide rail (42) comprises a first section (43a) and a second section (43b) which are joined together through a connecting region (55). first section (43a) defines an angular start position (54) for guiding aspect (46) and second section (43b) defines an axial stop position (56) for guiding aspect (46). when the dose element (22) is rotated in the dose setting direction, the guiding aspect (46) is angularly shifted from the angular starting position (54) to the connection region (55), the spring element (26) ) is torsionally oriented, the spring-oriented element (26) tending to angularly shift the guiding aspect (46) to the angular starting position (54). when the guiding aspect (46) passes the connection region (55), the guiding aspect (46) enters the second section (43b) and is moved axially in a proximal direction with respect to the housing (2) to the position of axial stop (56). In the axial stopping position, the reduction in orientation relative to the torsion is prevented by the mechanical cooperation of the guiding aspect (46) and the second section (43b).conjunto para um dispositivo de distribuição de fármaco a presente invenção refere-se a um conjunto para um dispositivo de distribuição de fármaco (1) que compreende um alojamento (2) , um elemento de dose (22), um trilho de guia (42) e um elemento de
