A fluid coupler comprising: a valve body defining a valve body axis; a valve arrangement for opening and closing fluid flow through the valve body; and a valve mounting housing in which the valve body is mounted via an alignment compensation arrangement, the valve mounting housing defining a central mounting housing axis, the alignment compensation arrangement including a compensation sleeve, a compensation ring, and a compensation spring mounted within the valve mounting housing, the compensation spring being configured to bias the compensation sleeve and the compensation ring axially apart from one another, the valve body extending through the compensation sleeve and compensation ring such that the compensation sleeve and the compensation ring are positioned radially between the valve mounting housing and the valve body, the alignment compensation arrangement being movable within the valve mounting housing between an extended state and a compressed state, the compensation ring being spaced axially further from the compensation sleeve when the alignment compensation arrangement is in in the extended state as compared to the contracted state, the compensation spring biasing the alignment compensation arrangement toward the extended state, a tapered interface being defined between the valve body and at least one of the compensation sleeve and the compensation ring, wherein the tapered interface automatically positions the valve body in a centered position in which the valve body axis and the central mounting housing are co-axially aligned when the alignment compensation arrangement moves to the extended state, and wherein the tapered interface causes the compensation sleeve and the compensation ring to be moved axially toward one another when a tilt load or radial translation load is applied to the valve body thereby allowing the valve body to be angularly displaced or radially translated relative to a centered position, characterized in that the tapered interface includes nested conical tapers. a valve body defining a valve body axis; a valve arrangement for opening and closing fluid flow through the valve body; and a valve mounting housing in which the valve body is mounted via an alignment compensation arrangement, the valve mounting housing defining a central mounting housing axis, the alignment compensation arrangement including a compensation sleeve, a compensation ring, and a compensation spring mounted within the valve mounting housing, the compensation spring being configured to bias the compensation sleeve and the compensation ring axially apart from one another, the valve body extending through the compensation sleeve and compensation ring such that the compensation sleeve and the compensation ring are positioned radially between the valve mounting housing and the valve body, the alignment compensation arrangement being movable within the valve mounting housing between an extended state and a compressed state, the compensation ring being spaced axially further from the compensation sleeve when the alignment compensation arrangement is in in the extended state as compared to the contracted state, the compensation spring biasing the alignment compensation arrangement toward the extended state, a tapered interface being defined between the valve body and at least one of the compensation sleeve and the compensation ring, wherein the tapered interface automatically positions the valve body in a centered position in which the valve body axis and the central mounting housing are co-axially aligned when the alignment compensation arrangement moves to the extended state, and wherein the tapered interface causes the compensation sleeve and the compensation ring to be moved axially toward one another when a tilt load or radial translation load is applied to the valve body thereby allowing the valve body to be angularly displaced or radially translated relative to a centered position, characterized in that the tapered interface includes nested conical tapers.
