A turbomachine comprising:

• a rotor rotatably mounted within a stator, the rotor including:
• a shaft;
• and
• at least one rotor wheel mounted on the shaft, each of the at least one rotor wheels including:
• a rotor wheel attachment slot;
• a blade having a blade attachment member, wherein a shape of the blade attachment member is not complementary to a shape of the rotor wheel attachment slot;
• and
• an assembly for affixing the blade attachment member to the rotor wheel attachment slot, the assembly comprising:
• an adaptor member disposed between the blade and the rotor wheel, the adaptor member including
• an adaptor attachment slot that is complementary to the blade attachment member,
• an adaptor attachment member that is complementary to the rotor wheel attachment slot;
• and a coverplate member, the coverplate member including
• a coverplate attachment member that is complementary to the rotor wheel attachment slot,
• a hook-shaped feature disposed on a radially inward end of the coverplate attachment member for engaging the adaptor member, wherein the hook-shaped feature axially retains the adaptor member relative to the coverplate member;
• wherein the blade attachment member is axially inserted into the adaptor attachment slot,
• wherein the coverplate member matingly engages a first face of the adaptor member, and
• wherein the assembled adaptor attachment member and coverplate attachment member are axially inserted into the rotor wheel attachment slot.
