An encoder device includes: a housing (10); a hub (4) arranged in the housing (10), the hub (4) arranged to carry an encoder disk (41), the hub (4) rotatable in the housing (10); and a gapping and centring device carried by the housing (10) and including a slide (51) that is movable between a first position and a second position. The slide (51) in the first position is arranged to urge the hub (4) into a predetermined axial and radial position relative to a portion of the housing (10), and the slide (51) in the second position is arranged to permit axial and radial movement of the hub (4). The slide (51) is arranged on an axial side of the housing (10) opposite to an axial side on which the housing (10) is to be mounted to a device to be measured, and the slide (51) in the first position and in the second position does not extend beyond a radial periphery of the housing (10).
