First and second coupling members on the base and roller tube support permit an adjustment of the alignment of the roller tube support, and the end of a roller tube mounted thereon, relative to the base. Also provided is a blind fabric alignment device for a roller tube of a multi-tube roller blind. The alignment device comprises a drive coupling body securable to an end of a roller tube of the blind, a driven member mounted to the drive coupling body, a torque transfer mechanism secured to the driven member, and an adjuster. The torque transfer mechanism transfers rotational torque from the driven member to the drive coupling body through the adjuster. The adjuster permits an alteration of the rotational position of the driven member relative to the drive coupling body. ## Claims ### Claim 1 A roller tube end coupling for mounting to a hollow end of a roller tube of a roller blind, the end coupling comprising: a body for securing to the end of the roller tube, said body having a generally right cylindrical configuration with a generally hollow interior and an exterior diameter such that when said body is received within the hollow end of the roller tube rotation of said body cause rotation of the roller tube, a first gimballed sleeve received at least partially within the hollow interior of said body, said first gimballed sleeve having a generally hollow interior, a second gimballed sleeve received at least partially within the hollow interior of said first gimballed sleeve, said second gimballed sleeve releasably securable to a driven or drive member of an adjacent roller tube, said first gimballed sleeve secured to said body by a first pair of pins that form a first pivot axis to permit said first gim balled sleeve to pivot relative to said body, and said second gimballed sleeve secured to said first gimballed sleeve by a second pair of pins that form a second pivot axis to permit said second gimballed sleeve to pivot relative to said first gimballed sleeve, wherein said first and second pivot axes are orthogonal. ### Claim 2 (depends on 1) The roller tube end coupling as claimed in claim 1 wherein said first pair of pins intersect said body at diametrically opposite locations on said body, and said second pair of pins intersect said first gimballed sleeve at diametrically opposite locations on said first gimballed sleeve. ### Claim 3 (depends on 1) The roller tube end coupling as claimed in claim 1 wherein an exterior surface of said first gimballed sleeve is convex. ### Claim 4 (depends on 2) The roller tube end coupling as claimed in claim 2 wherein an exterior surface of said second gimballed sleeve is convex. ### Claim 5 (depends on 3) The roller tube end coupling as claimed in claim 3 wherein the second gimballed sleeve has a generally centrally located bore to receive the driven or drive member therein, such that rotation of said second gimballed sleeve causes rotation of said first gimballed sleeve and said body. ### Claim 6 (depends on 1) The roller tube end coupling as claimed in claim 1 wherein said body includes a plurality of pairs of openings for receiving said first pair of pins, said openings arranged in diametrically opposed rows in said body, where said rows are parallel to the longitudinal axis of said body, such that the receipt of said first set of pins within different pairs of openings in said body permits a location of said first gimballed sleeve to be altered along a longitudinal length of said body.
