An adjustment mechanism for a roller blind. The adjustment mechanism comprises (i) an adjustment spring housing securable to an end plate of the roller blind such that when so secured the housing does not rotate independent of the end plate, (ii) a balancing spring coupler at least partially receivable within the adjustment spring housing, the balancing spring coupler having an outer end securable to an end of a balancing spring of the roller blind, (iii) an adjustment spring, the adjustment spring transferring rotational torque between the adjustment spring housing and the balancing spring coupler, and (iv) an adjustment shaft positioned at least partially within the adjustment spring housing. Rotation of the adjustment shaft causes a rotation of the balancing spring coupler and the adjustment spring relative to the adjustment spring housing to increase or decrease the torsional loading of the balancing spring.
