A drug delivery device comprises a housing () and an expelling assembly with a piston rod (), a drive tube () with an outer surface and a scale drum () arranged between the drive tube and the housing, the scale drum being coupled to the housing and the drive tube outer surface. The device further comprises a drive spring () arranged between the housing and the drive tube, and setting means () allowing a user to simultaneously set a dose amount to be expelled and strain the drive spring correspondingly by rotation of the drive tube. The scale drum is coupled to the drive tube via a spline connection, wherein the drive spring is arranged proximally of the spline connection when the spline connection is in its proximal-most position.
