In combination, a self-contained adjustable post for connecting an underground rotary valve to an above ground valve operator, valve position indicator, or the like. An elongated generally hollow housing portion, comprising a pair of relatively non-rotatable telescoped members, extends upwardly from the underground valve to ground level whereby the housing may be telescopically adjusted to accommodate rotary valves buried at variable depths. A connecting shaft portion, comprising a pair of relatively non-rotatable telescoped members, is disposed within the housing, connected at its lower end to the rotary valve shaft to rotate with the valve shaft, and extending at its upper end to ground level within the housing. The upper end of the connecting shaft and the housing are interconnected either directly or by means of the valve operator or valve position indicator whereby the length of the connecting shaft is automatically and simultaneously telescopically adjusted as the length of the housing is telescopically adjusted.
