1. A gap seal for sealing a gap between two adjacent components comprising:two components having a gap therebetween defining a gap plane, each component comprising one groove that is open towards the gap, each groove having a bottom and defining a longitudinal direction, the two grooves facing each other in the gap; a mutual sealing body projecting into both grooves, two sections of the sealing body comprising straight outer sides defining angles therebetween; in each groove, a compensation body movably positioned transversely to the longitudinal groove direction and parallel to the gap plane; each compensation body sealingly abutting the groove bottom of the corresponding groove; each compensation body having a V-shaped receiving groove that is open towards the other compensation body, each V-shaped receiving groove having straight inner sides; the sealing body having a rhombus-shaped cross-section and projecting into both receiving grooves; the straight inner sides of each receiving groove being angled towards each other at the same angle as the straight outer sides of the section of the sealing body projecting into them; and in each receiving groove, at least one outer side of the sealing body sealingly abutting the corresponding inner side of the receiving groove with surface contact. 2. A gap seal according to claim 1, wherein the components are movable relative to each other in such a way that the gap width may change, and wherein the sealing body and the receiving grooves are dimensioned so that when a minimum gap width is realized, the components abut each other.3. A gap seal according to claim 1, wherein the groove bottom in both grooves is level and extends parallel to the gap plane, and wherein each compensation body has a level bottom that abuts the groove bottom of the corresponding groove with surface contact.4. A gap seal according to claim 1, wherein each groove has a U-shaped cross-section including facing, straight inside walls of the groove extending parallel to each other and vertical to the gap plane;wherein each compensation body has a U-shaped outer cross-section including straight outside walls facing away from each other and extending parallel to corresponding inside walls of the groove; wherein a distance between the outside walls of each compensation body is smaller than a distance between the inside walls of the corresponding groove. 5. A gap seal according to claim 1, wherein at least one of the components comprises an element of a turbine or a compressor, the element selected from the group consisting of a guide vane, a rotor blade, and a heat shield element.
