1. A filter holder particularly for espresso coffee machines, comprising: a cup-shaped body which has a substantially cylindrical shape with respect to a central axis of said cup-shaped body, said cup-shaped body having a side wall and a bottom, and said cup-shaped body being open in an upward region for fitting on an espresso coffee machine and having an opening in said bottom which is arranged on said central axis of said cup-shaped body for the passage of an extracted beverage; andan adapter which is fitted and arranged inside said side wall of said cup-shaped body, said adapter being cylindrical and comprising a base and a side wall which form an extraction chamber adapted to accommodate a substance in powder form from which a beverage is to be extracted, said base of said adapter being supported above said bottom of said cup-shaped body, and said adapter being fixed to said cup-shaped body such that said adapter is able to freely rotate coaxially with respect to said cup-shaped body,said adapter being fixed to said cup-shaped body inside the cup-shaped body such as to be adapted to prevent an axial movement of said adapter in a direction toward said upward region of said cup-shaped body and away from said bottom of said cup-shaped body, such that said axial movement of said adapter is blocked and simultaneously said adapter is free to rotate coaxially with respect to said cup-shaped body, andsaid side wall of said adapter having a height sufficient to form an internal surface of said adapter that is adapted to sealingly engage a gasket of an extraction assembly to form said extraction chamber. 2. The filter holder according to claim 1, wherein said side wall of said adapter forms an upper opening for watertight fitting on said extraction assembly and a beverage conveyance element protrudes from said base of said adapter, said conveyance element being coaxial with respect to said central axis and passes through said opening on the bottom of said cup-shaped body. 3. The filter holder according to claim 1, wherein said adapter can be disengaged manually from said cup-shaped body in order to remove said adapter from said cup-shaped body. 4. The filter holder according to claim 2, wherein said adapter is snap-fit to said cup-shaped body. 5. The filter holder according to claim 4, wherein said adapter includes at least one tab, which is arranged externally on said conveyance element for snap engagement with the edge of the bottom opening of said cup-shaped body. 6. The filter holder according to claim 5, further comprising a circular groove, which is arranged around the edge of the bottom opening of said cup-shaped body and within which a free end of said tab engages so as to slide within said groove during a rotation of said adapter about its own axis. 7. The filter holder according to claim 1, wherein said adapter is adapted to contain completely a prepackaged dose of ground roasted coffee. 8. An assembly for extracting a beverage from a substance in particulate form, comprising: a bell-shaped element, which has a base and a side wall which lies around an axis for fitting on a beverage extraction machine;a ring, which is fitted coaxially and externally with respect to said bell-shaped element;a filter holder according to claim 1, wherein said cup-shaped body of said filter holder is fitted removably on said ring according to a bayonet coupling by means of outwardly extending protrussions of said side wall of said cup-shaped body in order to form an extraction chamber together with at least one portion of the base of said bell-shaped element, the height of said extraction chamber being adjustable according to the angular position of said filter holder about said axis, said extraction chamber comprising a gasket which removably sealingly engages an inner surface of the adapter of said filter holder during the steps for fitting and removing the filter holder with respect to said ring. 9. The extraction assembly according to claim 8, wherein the base of said bell-shaped element comprises a hollow axial protrusion, which is directed substantially toward the inside of said bell-shaped element and is adapted to engage in an upward region a hot water injector of a machine for extracting beverages, the internal cavity of said protrusion comprising a nozzle for distributing the hot water in said extraction chamber, said base of said bell-shaped element being coupled elastically to an upper filter of said extraction chamber, said filter being able to move axially. 10. The extraction assembly according to claim 8, further comprising a complementary ring, which forms an upper guide for said bayonet coupling, said upper guide being adapted to guide downwardly the movement of the filter holder during the removal in a rotary direction of the filter holder from the ring. 11. A filter holder particularly for espresso coffee machines, comprising: a cup-shaped body which has a substantially cylindrical shape with respect to a central axis of said cup-shaped body, said cup-shaped body having a side wall and a bottom, and said cup-shaped body being open in an upward region for fitting on an espresso coffee machine and having an opening in said bottom which is arranged on said central axis of said cup-shaped body for the passage of an extracted beverage; andan adapter which is fitted in said cup-shaped body and is cylindrical in order to form an extraction chamber adapted to accommodate a substance in powder form from which a beverage is to be extracted, said adapter being fixed to said cup-shaped body such that said adapter is able to freely rotate coaxially with respect to said cup-shaped body,said adapter being fixed to the cup-shaped body such as to be adapted to prevent an axial movement of said adapter in a direction toward said upward region of said cup-shaped body and away from said bottom of said cup-shaped body, such that said axial movement of said adapter is blocked and simultaneously said adapter is free to rotate coaxially with respect to said cup-shaped body; andwherein said adapter comprises a side wall which forms an upper opening for watertight fitting on an extraction assembly and comprises a base from which a beverage conveyance element protrudes which is coaxial with respect to said central axis and passes through said opening on the bottom of said cup-shaped body, andsaid side wall of said adapter having a height sufficient to form an internal surface of said adapter that is adapted to sealingly engage a gasket of said extraction assembly to form said extraction chamber. 12. The filter holder according to claim 11, wherein said adapter can be disengaged manually from said cup-shaped body in order to remove said adapter from said cup-shaped body. 13. The filter holder according to claim 11, wherein said adapter is snap-fit to said cup-shaped body. 14. The filter holder according to claim 13, wherein said adapter includes at least one tab, which is arranged externally on said convenance element for snap engagement with the edge of the bottom opening of said cup-shaped body. 15. The filter holder according to claim 14, further comprising a circular groove which is arranged around the edge of the bottom opening of said cup-shaped body and within which a free end of said tab engages so as to slide within said groove during a rotation of said adapter about its own axis. 16. The filter holder according to claim 11, wherein said adapter is adapted to contain completely a prepackaged dose of ground roasted coffee.
